YARN AND THREAD GUIDE.

Application filed November 2, 1922. Serial No. 598,560.

T 0 all whom it may concern:

Be it known that I, FRED W. EAs'roN, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Yarn and Thread Guides, of which the following is a specification. g

This invention relates to certain new and useful improvements in yarn or thread guides and the primaryv object thereof 1s to provide a guide for use in connection w th spinning, twisting or similar machlne which has two series of confronting teeth between which the thread passes and which engage and prevent the passage of knots, fioats and other irregularities formed in the thread or yarn, to thereby preclude the spinning of the knots into the finished yarn.

The invention further aims to provide a device of this kind which can be easily and quickly adjusted to vary the spaces between the two series of teeth, and which also can be easily and quickly manipulated to release knots or other irregularities in the thread or yarn, upon the thread being arrested in its movement by engagement with the blades carrying the teeth.

The invention further aims to provide a structure which is of simple and economical construction, and wherein the parts are compactly related.

The invention has still further and other objects which will be later set forth and manifested in the course of the following description.

In the drawings,

Figure 1, is a rear elevation of the lnvention, and

Figure 2, is an end elevation looking from the left of Figure 1.

In proceeding in accordance with the present invention, a frame is employed which consists of a member 1 shaped to engage about one side of a rod or other support 2, the opposite side of the rod be1ng engaged by a member 3 which is secured to the frame 1 by means of a nut and bolt 4.

The upper end of the frame 1 extends above the supporting rod2 and is bifurcated at 5. A blade 7 is formed with a horizontal series of teeth or serrations 8, the teeth being each of substantially V-form. The blade 7 is in offset relation to the supporting rod 2 and depends from a carrier ti formed with ears 9 which latter engage on opposite sides of the upper end of the frame 1, a

downward direction. A finger piece 12 is.

formed on the carrier 8 and thereby the blade to be moved about pivot 10 to release the yarn or thread for the purpose of removing a caught knot or float. The front end of the carrier 8 is to permit the latter formed with a boss 13 through which a screw 14 is threaded, the lower or free end .7 of the screw bearing against a stop 15 in the form of a lug orfinger which extends outwardly from the frame 1. A lower blade 16 is carried by the frame 1 and is formed with teeth or serrations 17 similar to the teeth 8 of the blade 7. The teeth 8 and 17 lnterengage, that is to say the teeth of one blade enter the V-shaped spaces existing between the teeth of the other blade. 7 In operation, the thread is passed through the space between the two series of teeth, and since the thread moves through the space between two lower adjacent teeth and beneath the apex of the upper tooth which projects in said space, it will be seen that the thread is not only effectually guided but that the three teeth are very effective and cooperate in preventing the passage of knots or floats. In order to release a caught knot or other irregularity in the yarn or thread, it is merely necessary forthe operator to press down on the finger piece 12 thereby raising blade 7, which latter swings outwardly and upwardly from the teeth of the blade 16. It will also be seen that the thread may be engaged with various teeth alon the lengths of the blades, and if the thread should for any reason ride up along the side of either of two adjacent teeth, itwill drop down into engagement with the succeeding tooth, so that the operation is unimpaired. The downwardly extending pin 18 shown in broken lines Figure 1, may be attached to the blade 7 to prevent the yarn or thread from passing beyond the teeth of the blades. Having thus described my invention, what I claim as new and desire to secure by Letters Patent is L111 a thread guide, a pair of opposed members each formed with a series of teeth, said teeth intermeshing and being spaced to receive the thread through the space formed between a tooth of one member and the cooperating tooth on the other member and in a direction at right angles to the pitch circles of said teeth.

2. In a thread guide, a pair of opposed blades each formed with a line of teeth, said teeth intermeshing and being spaced to receive the thread through the space formed tween a side edge of the tooth of one blade and the adiacent side edge of the cooperating tooth of the other blade. and means to support the blades so that the line of the teeth is at right angles to the line of travel of the thread.

3. In a thread guide, a pair of opposed members one formed with a pair of spaced teeth and the other with a tooth which extends into the space between the pair of teeth so as to receive the thread through the space between said tooth of one member and the adjacent tooth of the other member and in a direction at right angles to the pitch circles of the teeth.

4. In a thread guide, a pair of opposed members one formed with a pair of spaced teeth and the other with a tooth which extends into the space between the pair of teeth so as to receive the thread through the space between said tooth of one member and the adjacent tooth of the other member and in a direction at right angles to the pitch circles of the teeth, and means to vary the spaces between the teeth to permit of varying gages of thread to pass therethrough.

5. In a thread guide, a pair of opposed members each having undulations which confront, and intermesh with one another in spaced relation, and means to support the members in a plane at an angle to the path of travel of the thread so that the latter passes through the space between an undulation of one member and the cooperating undulation of the other member and in a direction at rightangles to the pitch circles of the undulations.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

FRED \V. EASTON.
